How to get multiple parts of text from string?

Question

C++ / C#

Let's say I have the following:

string long = "kfkfkkfppepd0d03k31word=1<3!oleg!3>1flakoekfml2laz[-1dom3-]"

And I create one more variable:

string long_part1 = "";
string long_part2 = "";

How to make long_part1 fit word oleg from long and long_part2 fit word dom?

Answer 1

class Program {

        static void Main(string[] args) {

            string longer = "kokokoko<!3oleg!3>lololo[2!dom2!]";

            string name = SearchWordInMassive(longer, "!3");  //longer1
            string adress = SearchWordInMassive(longer, "2!"); //longer2 
        }
        
        private static string SearchWordInMassive(string massiveWords,string restrictionCharacters) {
            string word = "";
            int startIndex = massiveWords.IndexOf(restrictionCharacters) + restrictionCharacters.Length;
            int lastIndex = massiveWords.LastIndexOf(restrictionCharacters);
            int lengthWord = lastIndex - startIndex;
            word = massiveWords.Substring(startIndex, lengthWord);
            return word;
        }
    }

Maybe it could be smaller, so I'm not sure.
An array of words is passed to the method, letters - 1 parameter, 2 is what your words are limited to. It is necessary that the limiters on the sides are the same, that is, !3 oleg !3
